When UFC featherweight Chan Sung Jung faces champion Jose Aldo at UFC 163, he will attempt to achieve a feat that’s only occurred once and hasn’t taken place in more than seven years. Specifically, Aldo’s only career stumble came in November 2005 before “Scarface” had shown up in WEC. He’s since gone on to win fifteen straight fights including victories over Chad Mendes, Urijah Faber, Kenny Florian, Cub Swanson, and Frankie Edgar.

The 13-3 Jung knows he’s in for a true test when the two square off, but “The Korean Zombie” believes his skills are certainly solid enough to snatch Aldo’s strap.

“Aldo is close to perfect as a fighter and I realize that I have shortcomings in my game,” said Jung in an interview with MMAWeekly. “On paper it may not look like a good fight, but in MMA things happen that you can’t predict on paper.”

Jung isn’t certain if it will be his BJJ or stand-up securing the victory, but he does know one area he’ll have to surpass Aldo in if hoping to pull off the upset.

“I think the difference may come down to the mental game,” offered Jung in assessment, calling the opportunity to clash with Aldo a longtime dream he won’t take for granted.

UFC 163 is scheduled for August 3 in Rio de Janeiro, Brazil. Other bouts on the card include Demian Maia-Josh Koscheck and Phil Davis-Lyoto Machida.
